Backlight module and liquid crystal display device

Abstract

A backlight module and a liquid crystal display device, the backlight module comprises a back plate ( 101 ) and a fixing frame ( 102 ) firmly connected with the back plate ( 101 ), and further comprises a light guide plate ( 106 ); the fixing frame ( 102 ) is provided with a protrusion ( 111 ) extending towards an inner side of the backlight module, the light guide plate ( 106 ) extends into a region under the protrusion ( 111 ) of the fixing frame ( 102 ) and is pressed by the protrusion ( 111 ); the light guide plate ( 106 ) is provided with a lamp fixing hole ( 112 ) configured to fix a lamp. A liquid crystal display device comprising the backlight module is further disclosed.

The invention claimed is: 
     
       1. A backlight module, comprising: a back plate and a fixing frame firmly connected with the back plate, and further comprising: a light guide plate; wherein the fixing frame is provided with a protrusion extending towards an inner side of the backlight module, the light guide plate extends into a region under the protrusion and is pressed by the protrusion; the light guide plate is provided with a lamp fixing hole configured to fix a lamp;
 wherein the lamp comprises LED luminous members, and 
 wherein the lamp further comprises a lamp fixing strip configured to be connected with the LED luminous members, and pressed directly by the light guide plate. 
 
     
     
       2. The backlight module according to  claim 1 , wherein the protrusion directs to a film material in the backlight module. 
     
     
       3. The backlight module according to  claim 1 , wherein a light emitting surface of the lamp closely contacts with a light incident surface of the light guide plate. 
     
     
       4. The backlight module according to  claim 1 , wherein the lamp fixing hole and the lamp have a same size. 
     
     
       5. The backlight module according to  claim 1 , wherein the protrusion is provided with a curtain tape configured to fix a panel. 
     
     
       6. The backlight module according to  claim 1 , wherein a reflective plate is provided between the light guide plate and the back plate. 
     
     
       7. A liquid crystal display device, comprising: the backlight module as claimed by  claim 1 .
